Air-Powered STA-10x-4M Series Pumps

The STA-10x-4M models use a 4-way valve in order to operate double-acting cylinders. The 4 way valve is used to operate the air pressure. The standard model, STA-101-4M has an anodized aluminum, 98 cu. in. reservoir. Other sizes of both aluminum and plastic reservoirs are available.

These pumps are made of lightweight, durable heavy-duty anodized aluminum to provide toughness while reducing overall weight. They operate in all types of weather over a wide temperature range. They can safely deliver up to 10,000 psi of hydraulic pressure for a variety of applications. These models provide excellent oil delivery resulting in more work in less time. They utilize a two-stage release for fast ram return while keeping hydraulic shock to a minimum.
